I recently shifted to new home with metal roof.
There is lot of expansion ad contraction popping noise especially at night.
Builder and few roofers told me that this is normal and cannot be avoided.
But I am thinking if there is a way to avoid them completely, it will be great as I am a light sleeper and these noises are affecting me a lot.
Any advice that can help me sleep will be helpful? :)
Go for a walk around the neighborhood and when you spot a house with an old gal roof and the garden looks old knock on the door ans ask if they have any pointers.
